IMPROVE!) COALLCAR AND TRACK.

The Schedule referred to in these Letters Patent and making part of the saine.

To all whom it may concern.-

Be it known that I,'=`GEoReE Maerz, of Pottsville, in, the county of Schuylkill, and State of Pennsylvania, have invented a new.and improved -Hoisting-Machine for running' up slopes; and ldozhereby declare that'the following' is afull, clear, and exact description of the construction and operation ot' the same, reference being had to the accompanying drawings, making a part'of this specification, in whichl Figure l is a longitudinalvertical section, and

'Figure 2 is an elevation of the lower end of the tracks with the gangway.

This .invention relates-to the propulsion ot' cars ladenwith coal, from the `gangway of a mine, up an inclined way to the surface, by meansvot' a motive truck, separate from the cars,.and running upona track above them.

Theinvention consists-in providing said truck with a platform, either fixed or adjustable, which shall serve as a cover for the coal-car. Also, in providing hooks upon the motive-truck and journals upon the coal-car, and so arranging the two` vehicles with respect to each other that the said hooksand journals may be automatically connected anddisconnected, for dumping, lowering, and releasing-purposes. Also,

Iin so combining the costear and motive-truck thatl theone may propel the other by simple contact, `witl1' out other connection, In the drawings- A is a coal-car, supposed to be placed in the gauge way of a mine, and running upon aninclined track, a.

B is a motive-truck, .placed directly o\'erthe car A,

and running upon an inclined track, b.-

'lhe two inclined tracks should be placed far enough apart to enable the coal-car when loadedto be run under the motive-truck.

The vlatter hasa platform, b, on its rear end, of a capacity to cov-er the coal-car, and prevent the escape. of the contents ofthe latter when moving up the incline loaded.

The platform l1 should be adjustable with respect tothe truck B, so as to admit under it a load ofcoal of any height.

'The advantage of placing the cover of the coal-car upon the motive-truck is, that when the latter arrives at the end lof its track, and is ready to dump its load` upon .the chute C, its cover is borne o' by the truck whose track b does -not terminate at the same point as the track a, and thus nothing prevents the delivery of the coal.

` The tracks wand b run parallel until near the upper end of the former, whel'e the upper .track assumes a steeper pitch than the lower.

This brings the reall ends of the truck and car nearer together than when they run parallel, and causes the hooks 112W, placed upon the vrear end of the former, to take hold of the journals a? ai, project-A inglrom both sides ofthe rear endet' the latter.

When the tiont end of the coal-car is almost at the terminus of` the track' a, the hooks l)2 raise' the rear end of the car, and, it' the truck l be drawn far enough forward, the coal-car will be suspended perpendicularly, by means of its journals, upon the hooks, and all its contents will fall upon Jthe chute C. On

returning, the hooks gradually lower the car till it assumes itsproper place on the track.

At the lower terminus the upper track rises out of' parallelism with the lower one, vand causes the hooks and journals to separate, sothat the coal-car may ruu Onward into the mine and be loaded up. Itfshould be noticed that, by reason ot' the peculiar directions; of'tlle tracks, the couplingglr and unconplinpr ofthehooks b? and journals a? is'automatic.

The propulsion ot' the coalcar, ii'onithe bottom of the incline to near its upper termini'is, is effected by the rear axleof the truck 'B coming in contact with the rear end vof the car.

The-hooks and journals do not come into connection till near the end of the drawing. This connection, by simple contact, enables the ends ofthe truck and ear to separate, without obstacle or unshackling,

when' it becomes necessary 4that they should do so just previous to the dumping-operation.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. A motive-truck7 so constructed and adapt-ed to the coal-car that its platform sha-ll serve as a cover to the car.

2. A eoalcar and motive-truck, constructed and adapted to cach other, so. as to automatically connect and disconnect themselves, subst-antiallyns and'for the purpose specified.

3. The described arrangement of coal-car and mq- 'tive-truck with each other, and with the tracks u b,

which are constructed as described, whereby the car is-propelled forward by means oithe motive-truck, substantially as and for lthe Apurpose set forth.

To the above specification of my improvemcnt,[ have set my hand, this 17th day of August, 1869.
